Recommendation ITU-T L.1202 is provided as a complement to Recommendation ITU-T L.1201,which describes the architecture of direct current (DC) power systems with an up to 400 VDC information and communication technology (ICT) equipment interface.The up to 400 VDC ICT equipment interface is described in Recommendation ITU-T L.1200.Recommendation ITU-T L.1202 provides a framework for assessing performances of up to 400 VDC power feeding systems and the savings incurred when compared to other power feeding systems such as the ?48 VDC power system and the AC uninterruptable power system (UPS) commonly used in information and communication technology (ICT) sites.This Recommendation deals with performance factors such as efficiency, reliability/availability and environmental impact.
